Polyaniline functionalized reduced graphene oxide (PORGO) is prepared by interfacial polymerization and then vertically oriented polyaniline‐graphene (PANI‐PORGO) nanocomposites based on PORGO are developed successfully by in situ polymerization. The morphology and structure are characterized by field emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), Fourier transform infrared spectra (FT‐IR), Raman spectra and X‐ray diffraction (XRD). The electrochemical tests indicate that the specific capacitance of PORGO and PANI‐PORGO is as high as 291 and 369 F/g, respectively, at the current density of 1 A/g. PANI—PORGO nanocomposite exhibits high electrochemical activity and enhanced cycle stability with a capacitance retention of 81.2% after 500 cycles at 10 A/g. © 2017 Wiley Periodicals, Inc. J. Appl.
